This cable is ideal for connecting Smartphones, MP3 players and tablets to a stereo receiver, speaker or other RCA-enabled device. It supports mobile devices containing a standard 3.5 mm auxiliary jack, which are commonly associated with headphones/ear buds. In fact, many of today’s audio components have this convenient input for easy hookups. Dual-shielding, polished metal molding and corrosion-resistant gold-plated connectors deliver crisp sounds and minimal signal loss. A compact, beveled step-down design connector tip gives a firmly secure connection, even when bulky cases are on your device. You can even charge your devices while in use (separate cable required).
